It might not be a file path problem but make sure you've tested that all out 1st

When running audio stuff from the exec node - you sometimes have to be explict about specifying what audio hardware to use.

I play an mp3 via an exec node and had to add in lots of stuff to get it work

mpg123  -a plughw:1,0 alexa.mp3

You might have to do something similar to hear your speech

It took a lot of googling to find out how to get mine to work
